10% Vitamin C & 5% Niacinamide Serum

The Asaya and Pilgrim serums present a compelling case for drugstore dupe status, primarily due to their shared core active ingredients. Both formulations deliver a robust dose of Vitamin C, a powerhouse antioxidant known for brightening and its role in collagen synthesis, alongside Niacinamide, which is excellent for barrier function and minimizing pores. Furthermore, the presence of Hyaluronic Acid across both ensures superior hydration, effectively plumping the skin.

While the ingredient overlap is significant, the Pilgrim serum notably boasts a higher concentration of Vitamin C at 15% compared to Asaya's 10%, which could translate to more potent brightening and antioxidant benefits for some users. However, if a gentler introduction to Vitamin C is preferred, or if you're seeking the more balanced multi-correctional approach offered by Asaya's specific 10% Vitamin C and 5% Niacinamide blend without the potential for increased sensitivity from a higher Vitamin C percentage, the original remains a strong selection.

The PHD 10% Vitamin C Brightening Serum is a strong dupe for the Asaya offering primarily due to their identical 10% concentration of Ascorbic Acid, the most effective form of Vitamin C for brightening and antioxidant benefits. Both also utilize Glycerin for foundational hydration and Hyaluronic Acid to plump and retain moisture, ensuring similar epidermal support and a common baseline for reducing hyperpigmentation and improving overall skin tone.

While both deliver on brightening, the Asaya serum includes 5% Niacinamide, a key ingredient for barrier support and larger pore refinement that the PHD formula lacks. This makes the original a better choice for those prioritizing comprehensive barrier health and significant pore improvement alongside their vitamin C; otherwise, PHD provides comparable brightening at a potentially more accessible price point.

The Revolution Beauty Targeted Under Eye Serum is a strong dupe for the Asaya 10% Vitamin C & 5% Niacinamide Serum primarily due to their shared functional components. Both formulations feature Glycerin for hydration and skin barrier support, alongside effective humectants like Propanediol, ensuring a similar foundational feel and immediate plumping effect. Crucially, the presence of Niacinamide in both at comparable concentrations addresses concerns like redness and pore appearance, making their core performance strikingly similar despite the differing hero actives on the label.

While the Revolution dupe delivers on core hydration and brightening, the Asaya original's higher concentration of Vitamin C offers a more potent antioxidant benefit and targeted collagen synthesis, which the Revolution product, focused on caffeine, doesn't fully replicate. Therefore, those prioritizing advanced anti-aging and comprehensive free radical protection will still find the Asaya original a worthwhile investment, despite the Revolution dupe's impressive ingredient alignment for general skin improvement.
